Can Food Be Medicine?

What a great program!!  It is interesting that feeding a person may cut health care costs in the long run. After some searching, it appears to be only in the Boston and Massachusetts area.  It may become a trend if the research indicates its benefits are cost effective. Another interesting fact is that the average age is stated at 49 “with a slew of chronic diseases” and they supposedly have a long waiting list.  Could the Standard American Diet (SAD) be a factor? Just a thought.

How the Food Industry Influences Nutrition Research

Industry funded studies are becoming a major influence on nutrition research that is already considered by some to have some important design limitations.

Headlines often proclaim that certain foods have healthy benefits not supported by science. These are used as marketing tools by the companies to describe their products in terms of what is described as a “health halo.” This practice contributes to false claims and the dissemination of nutrition misinformation which is already abundant.

One reason is that research in nutrition is not very well funded by very many sources; therefore, food companies often do provide the funds and at the same time gain their own benefits, i.e., increase their profits.

Super Fortified : “Foods” or Supplements?

Should You Get your Nutrients from Super-fortified Foods?

The label on the orange juice container says “calcium added”. The water bottle label says “fortified with vitamin C”; the energy drink s is “fortified with 23 added vitamins and minerals.” Do you need all these extra nutrients ?

These foods may actually act like dietary supplements. If you eat nutritious unprocessed whole foods, you probably do not need fortified foods and even may go over the Tolerable Upper Intake Levels (UL).

The UL is a set of values that are well above the needs of everyone in the population and represents the highest amount of the nutrient that will not cause toxicity symptoms in the majority of healthy people. As intake rises above the UL so does the risk of adverse health effects.

To establish a UL, a specific adverse effect is considered. For example, for niacin, the ill effect is flushing, and for vitamin D it is calcium deposits in soft tissue or kidney damage. For vitamin C it is digestive disturbances. For some nutrients, these values represent intake from supplements alone; for some, intake from supplements and fortified foods, and for others, total intake from foods, fortified food, water and nonfood sources and supplements. For some nutrients, data are insufficient to establish a UL.

“In traditional foods, the amounts of nutrients are small and the way they are combined limits absorption, making the risk of consuming a toxic amount of a nutrient almost nonexistent. On the other hand, this risk rises from eating an excess of a supplement or excessive servings of super-fortified foods.”

Young children may be particularly at risk for toxicity. “A new report says that “millions of children are ingesting potentially unhealthy amounts” of vitamin A, zinc and niacin, with fortified breakfast cereals the leading source of the excessive intake because all three nutrients are added in amounts calculated for adults.”

“Outdated nutritional labeling rules and misleading marketing by food manufacturers who use high fortification levels to make their products appear more nutritious fuel this potential risk, according to the report by the Environmental Working Group (EWG), a Washington, D.C.-based health research and advocacy organization.”

For example, if you drank the recommended two to three liters of fluids as water fortified with vitamin C, niacin, vitamin E and vitamins B6 and B12, you would exceed the UL for these vitamins. Then add two cups of fortified breakfast cereal and two protein bars during the day, your risk of toxicity increases even more. In many of these products, you also could be getting a not so healthy dose of sugar. Should we be consuming super-fortified foods without a thought? I think not. For a previous post, click HERE.
